My little blonde and I were very lucky when we bought our motor home, a Jayco Granite ridge, 2004 with 16000 miles on it. I had some idea on the ford E450 V-10,but as far as the coach we were newbies. We purchased it from a local couple that wanted to go back to a trailer. I new the coach needed tires so we put six firestone tires on right away. After we put the new tires on we took it out for a long drive.(about 60 miles) I did not like the way it drove. It seemed like it was all over the road. After two trips to the truck center and a lot of good info from the fine people on this forum we got the caster set right and away we went. We wish you luck and good travels.
